    • The Fig. 1A depictions and use of the standard s and p designations for the solvated electron states in bulk cavities are not meant to imply that, for all clusters, the excess electron must be bound in the interior of the clusters.

    • Each transient of regions b and c also includes a fast response-limited negative component due to the vertical detachment by the 800-nm pump pulse the photon energy of which exceeds that of the detachment to the neutraL For small clusters (n = 15, 20, and 25), the photodetachment process is increasingly favored over the transition to the bound p-state because of spectral shift (19), and this accounts for the small amplitude of the decay component (region 6) and the fact that neither the peak near time zero in region a nor the rise component in region c were detected.

    • -1 (15), and the vibrational frequencies to remain the same at the transition state. The initial internal energy of the cluster is assumed to be the highest thermal energy of stable clusters (dissociation energy); the drift time before excitation is ∼ 100 us, but clusters with higher internal energy may persist during this time. For the degeneracy factor of the reaction coordinate, we take half of the water molecules to be surface-bound and thus subject to dissociation.
